Prototrichia metallica is a species of slime mold from the order of the Trichiida and the only species of the genus Prototrichia . It is mainly found in the mountains.
description
Prototrichia metallica is a very variable species. The plasmodium is white. The fruiting bodies are in dense groups. They are orange-brown to dull brown, occasionally pink, short-stalked or a strongly tapered base, rarely nearly plasmodiocarp sporocarp with a diameter of 0.5 to 2.2 millimeters. The membranous peridium is translucent, thin and shiny, iridescent in color. Its surface consists of coarse-meshed, wrinkled lines along which it later disintegrates into individual parts.
The often irregular scalp usually consists of numerous yellow-brown, massive seeming, spirally banded threads that divide into multiple threads towards the outer end. The branches are often woven together in a spiral, occasionally they form a network. Many of the outer ends are fused with the upper part of the peridial wall. The spirals are occasionally missing. The spiked spores are pink, orange-brown to brown, individually yellow and have a diameter of 10 to 13, rarely up to 15 micrometers.
distribution
Prototrichia metallica is known from the mountainous areas of Tasmania , Europe and western North America. Finds from South America were not known until 1976; but there is no doubt that it will also be discovered there. It is known as “nivicol”, which means that it grows at the snowline when the snowmelts.
Systematics and research history
The species was in 1859 as Trichia metallica by Miles Joseph Berkeley , the genre in 1876 by Joszef Tomasz Rostafinski first described . Prototrichia was part of the Dianemidae for a long time , at times it was even regarded as a separate family Prototrichiaceae. However, since the late 1960s, it has been considered that they are part of the Trichiidae. Charles Meylan described another species of Prototrichia schroeteri in 1921 , the name is usually considered a synonym , but Nowotny thinks it is possible that a separate species is hidden behind it.
